CUTTING-TOOL;

United States, residing at Pendleton, in thecounty of Umatilla and Stateof Ore on, have invented certain new and useful mprovements inCutting-Tools, of which the following is. a specification, referencebeing had to the accompanying drawings.

This invention relates to improved cutting tools, and an. object is toprovidev a device of this kind especially adapted for turning up wornbearings for crank shafts, such as used on automobiles, gas tractors,trucks and the like.

A. further object involves the provision of a tool whichis simple,efiicient and practical in construction, capable of being cheaplymanufactured, and sold at a reasonable profit.

Another object involves the provision of a tool comprising a frame orbody having means adjacent which the work is disposed, in combinationwith a slide mounted in guides of the frame or body, with means foradjusting the slide, whereby a cutting member may be adjusted toward andfrom the work, sothat the work can be out to any suitable size ordiameter, and so that any suitable amount of material may. be moved fromthe crank shaft or other work operated upon.

While the design and construction at present illustrated and set forthis deemed preferable, it is obvious that as a result of a reduction ofthe invention to a more practical form for commercial purposes, theinvention may be susceptibleto changes, and the right to these changesis claimed, provided they are comprehended. within the scope of what isclaimed.

The invention comprises further features and combination of parts, aswill be herein after set forth, shown in the drawings and claimed.

Application filed April 3, 1920. Serial No. 371,079.

for clamping the cutting tool proper in position, in full lines and partin dotted lines. Referring more especially to the drawlngs, 1 designatesa frame or body member which may be any suitable shape and size,preferably elongated as shown, and may be made of any suitable material,preferably cast iron or steel, constructed in one piece as shown. Thisbody has an upstanding portion 2 which is at right angles to the face 3of the body. The body or frame is provided with an elongated slot 4, andguided in rabbets 5 of this slot is a slide block or cutting tool holder5. Passing upwardly through the block 5 is a cap screw or bolt 6. Thiscap screw or bolt 6 passes through clamping plate 7 and is threaded intoa tapped hole in the block. The forward upward portion of the slideblock has an angle recess or rabbet 5 in which a suitable cutting toolor knife proper 8 is secured. A plate 9 is mounted upon the upper faceof the slide block 5 and has one end overlying the cutting tool, inorder to clamp the tool in the recess 5". The plate 9 has a downwardlyextending lug 9 which fits into a cavity 9 in the upper part of theslide block, to assist in holding the plate 9 in position. The plate 9is held in clamping relation to the slide block and the cutting toolproper 8 by means of a cap screw or plate 9 in position and agalnst thecutting tool proper. However, it is to be noted that this cap screw orbolt does not clamp against the clamping plate 7, as the tension and theposition of the slide block is governed entirely by the cap screw 6.

The upstanding portion 2 of the body is provided with an angular recessor cavity comprising a pairof faces a, a. Thesefaces are formed oninclined planes extending at 45 angles from the upper face or plane 3 ofthe body. However, the faces a, a are constructed at right angles toeach other, as shown. These faces may be tempered. or

the faces may be constructed by providing finger is held in position.Also rising upinsert plates of tempered steel, and connected to theupstanding portion 2 in any suitable manner not shown. The upper end of.the portion 2 is provided with an opening 13, rectangular in crosssection for the reception of the shank 14 of the work holding finger 14.The work holding finger 14 extends at right angles to the finger 14 anddepends in a direction toward the work to be disposed adjacent the rightangle faces a, a, thereby cooperating with said faces, to assist inguiding the work during its rotation and at the time it is being turnedup. The shank 14 of the work holding finger fits the opening 13 closely.The shank 14 of the work holding finger has a reduced extension 14",which is threaded, and is adapted to receive a threaded nut 15. This nutcomprises a flange and a sleeve.

By means of this nut 15, the work holding wardly from the body or frame1 is an upright standard 16, which is cast upon the body of frame 1 andis provided with a tapped opening 16 for the reception of a threadedscrew 17, one end of which is swivelly connected to the slide block asat 17 in any suitable manner. A graduated sleeve 18 is suitablyconnected to the upright or standard 16, and is provided withgraduations 18 This graduated sleeve 18 extends in a direction from theblock 5, and

telescopically enters 'a sleeve 19 which is carried in anysuitable'manner by the hand wheel 21 having a handle 22. This hand wheel21 is suitably connected to the screw 17 preferably integrallytherewith, though not necessarily, and it is obvious that by adjustingthe screw in one direction or the other, the slide block may be movedtoward and from the work to be turned up. The sleeve 19 on its marginalbeveled edge is provided with a series of graduations 20, which, by therotating of the hand lever 21 are adapted to cooperate with thegraduations 18, for gaging the depth of the cutting tool proper 8. Inother words, when rotating the hand wheel, the slide block canbe movedtoward the work and the depth of the cutting tool proper 8 gagedaccording to the cooperation of the graduations 18 and 20 of the twotelescoping sleeves '18 and 19.

In the operation of the device, the work holding finger 14 is firstremoved by removing the nut 15 and sliding the finger out of the opening14 The body or frame may then be adjusted, and the work or crank'.-shaft to be turned up is then disposed in the.

cavity or recess of the upstanding part 2. The slide block is thenadjusted or moved back so that the tool proper 8 can be placed in therecess5" and clamped. However, before adjusting the block toward theupstanding part 2, the work or crank shaft to be-turned up is firstplaced in the angular cavity of the upstanding part 2 and the workholding finger replaced and the nut 15 turned home. The work guidingfinger 14 is positioned relatively close to the work or shaft to beturned up as indicated by the character I), after which the slidingblock is adjusted toward the work so that the cutting tool proper may bein a position to act upon the work, its depth being governed by theadjustment of the hand wheel.

Should it be desired to use the tool in connection with a lathe, theelongated shank portion 23 of the body is rested or supported on theways (not shown) of the lathe after which the lathe is operated slowly,

.the work to be turned up being rotated at the same time, in which casethe cutting tool proper will act upon the work, and turn it up as may bedesired.

From the foregoing it is to be noted that the present invention involvesvarious advantages over the old method. For instance, the present deviceis simple in construction, and furthermore the tool may be applied inposition with great ease. Furthermore, the cutting tool, mounted as itis, requires no vertical adjustments as it is always in correctposition. iVhen the device is used in connection with a lathe it is in aposition that insures the cuttings to fall away from the work and arenot carried around asis apt to occur with other tools now in use whichoperate in reverse positions. Furthermore, the tool operates in aposition leaving the work visible at all times, making it possible forthe operator to watch the progress of the work, which is very important,and is one of the main features or advantages of the device. However,the tool may be operated by hand,

-for instance, by holding the work or crank shaft to be turned up in avise, and applying the tool or device to the work in the manner aboveset forth, and after which the tool or device may be swung around thework by hand instead of the tool or device remaining stationary and theshaft or work to be turned up rotated as would be the case where thetool is operated in connection with a lathe.

The cap screw 10 operatively engaging the slot 4 constitutes additionalmeans for guiding the slot block when adjusted.
